<h1>Instructor Site: Code Examples</h1>

Numerous code examples in the CS:APP2e book are explicitly referenced by
pairs of annotated horizontal bars.  This page provides you with the
original copies of these files. For each file, we list the chapters
that reference it and the number of references to that file within
the chapter.

<ul>
<li>You can download a <a href="http://csapp.cs.cmu.edu/2e/code.tar">tarfile</a> that
contains all of the source files on this page. 

<!--
<li>You can also download another <a href="code-all.tar">tarfile</a> that
contains the complete set of source code examples for the manuscript,
including the smaller code fragments that are not referenced by the
annotated horizontal bars.
-->
